This function saves the current transformation settings on the stack so that you can restore it later if you need to.  You can restore it with the popmatrix function.  For example, if you run this code:





// save the current transformation matrix


swf_pushmatrix();





// translate this object


swf_definefont(3, "Mod");


swf_fontsize(5);


swf_definetext(3, "Hello", 1);


swf_translate(50, 50, 0);


swf_placeobject(3, 50);





// reload the last saved transformation matrix


swf_popmatrix();





swf_showframe();





Only the text "Hello" will be transformed to that location on the animation.  At first when I started using this library I didn't know what this did, but this is what I've found so far.  It can be very useful in animation.
